The curfew was put into place last night, the first time it has happened since 1944 apparently, but it was lifted again by this morning. It's still recommended to not go outside unless you have to, but not forbidden. (Very recently a car reportedly with four heavily armed people in it broke through a police barrier, driving towards Paris - nobody knows if directly connected yet..) It's still quite a tense atmosphere…
